Port Lincoln is the second-largest city on the lower Eyre Peninsula in the Australian state of South Australia. Nestled on the shore of Boston Bay, Australia's largest natural harbour, Port Lincoln opens eastward into Spencer Gulf. Port Lincoln is the largest city in the west coast region, and located approximately 174 miles (280 kilometres) from the capital city of Adelaide. Port Lincoln has a contrasting coastal landscape, ranging from sheltered waters and beaches to surf beaches and rugged oceanic coastline. The Great South Australian Coastal Upwelling System brings cold, nutrient-rich water into nearby waters of the Great Australian Bight and Spencer Gulf. This phenomenon supports lucrative fisheries, including that of the southern bluefin tuna and sardine, making Port Lincoln locally-renowned as the 'Seafood Capital of Australia'. The Eyre Peninsula has been home to Aboriginal people for thousands of years. The Nauo (south-western Eyre), Barngarla (eastern Eyre), Wirangu (north-western Eyre) and Mirning (far-western Eyre) being the predominant original cultural groups present at the time of the arrival of Europeans. Port Lincoln was discovered by Matthew Flinders under his commission by the British Admiralty to chart Australia's unexplored coastline. Flinders dropped anchor in Boston Bay in February 1802, and named the spot Port Lincoln after his native Lincolnshire in England. Port Lincoln was initially considered as the alternative site for the State's capital, but was subsequently rejected by Colonel Light in 1836 in favour of Adelaide; a lack of fresh water supplies was a major determining factor. The first settlers arrived in Port Lincoln in March 1839 aboard the Abeona, the Dorset and the Porter. There is an historic plaque at the First Landing site to commemorate the event. In the years since, Port Lincoln has evolved into one of the nation's biggest combined agricultural, fishing and aquaculture industries, with tourism becoming a major contributor towards the local economy. Port Lincoln offers ample opportunities to explore its unique blend of cultures and storied past. The local culture, traditions and storied past can be experienced during visits to any of Port Lincoln's scenic and informative museums.
